David Eustace said he makes his art by leaving canvases in Brooklyn's Gowanus Canal for as long as a month, the New York Post reported Wednesday.

"I see this as a play on the classic man-vs.-nature story. Except in this case, 'nature' happens to be a large industrial canal," he said.

Eustace said canvases look completely different depending on what season they come out of the water and that imperfections such as a stain left behind by little shrimp represent "a conversation between what I know about the canal and the actual experience of it."

The Brooklyn Arts Council gave Eustace a grant to show his pieces at a the BAG Gallery in Brooklyn until May 18, The Post said.
